To ctZZ whom, it may concern.-

Be it known that I, ALBERT CLAYTON PAL- MER, a subject of the Queen ofthe United Kingdom of Great Britain and Ireland, residing at Euroa, inthe Colony of Victoria, have invented certain new and usefulImprovements in Appliances for the Removal from and Replacing ofPneumatic Tires on Wheel- Rims; and] do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention consists of a novel appliance for manipulating-that is,removing fromand replacing on the rim-pneumatic cycle-tires, or ratherthat external tire which is usually termed thefcover, because it usuallyinoloses a thin inner tube, which, however, is always put on or removedwith ease once the tire-cover is disposed of. This disposal has hithertopresented much difficulty and caused damage to the cycle as well asundue loss of time so far as very many cyclists are concerned. Theoperations of removing and replacing the tire-cover are performed withrapidity and ease by this invention, and injury to the wheel-rim andcover is avoided. By my construction a movable rod is used, which is ator near one (herein called the lower) end adapted to be attached orpivoted to or on the axle of the wheel the tirecover of which is to beremoved or put on. At the other (herein called the upper) end of thesaid rod is a projection,consisting of any suitably bent'or hooked plateor arm, which is used for the purpose of removing the cover. On thatside of the said rod which is opposite to the said bent plate there isa'projection which serves as the axle of a wheel which hascircumferentially a flange or a groove and which is used for the purposeof putting the tire-cover upon the cycle-wheel rim. The distance betweenthe said bent plate (and flanged wheel) and the said lower end of therod is adjustable, and this is preferably accomplished by attaching saidbent plate (and wheel) to a sleeve fitting on and movable along the saidrod. A clamp is also used to temporarily hold the tire-cover to the rimfor the purposes hereinafter described. The appliance may be made ofbrass or any other strong material, while parts improved by beingcovered with rubber or with a smooth substance like celluloid may be socovered. The appliance is ordinarily constructed in combination with thebarrel of a tire-infiater of the ordinary tubular description, thebarrel, if weak, being strengthened-as, for example, by addinga piece oftubing over each 'endto carry the parts above described. The combinationwith an inflater renders the appliance far more useful and desirablethan it would otherwise be.

In the accompanying drawings, Figure 1 shows an edge view of acycle-wheel with my appliance, combined with an ordinary inflater,attached. The act of supporting and guiding the tire-cover into positionby means of a grooved wheel, so as to put it on the cycle wheel rim, ishere illustrated. Fig. 2 shows in side view part of the cycle-wheel withmy appliance attached; but in this instance it is in the positionoccupied in the act of removing the tire-cover by means of the bent orcurved plate aforesaid. The clamp is not used when removing the saidtire-cover, but only when replacing it; but it is shown in this view forconvenience of illustration in respect to the description of the saidreplacing. Fig. 3 shows an edge view of a cycle-wheel with my applianceattached, the position of parts when removing the tire cover beingillustrated. Fig. 4 shows a design, edge view, of my appliance Withoutan inflater, the place of which is in this instance .occupied by a barof metal having a movable sleeve which carries the bent plate and thewheel opposite it, before mentioned. Fig. 5 showsthe" bar in Fig. at inside view. Fig. 6 shows the clamp, which is useful to affix to the rimof the cycle-wheel to hold the tirecover at one part, so as to preventits slipping out when being manipulated at another part, as aforesaid.At the back end of this clamp is a lever which is useful for the purposeof lifting clear of the rim part of the tire-cover edge, in the firstinstance, before proceeding to insert the bent plate aforesaid, althoughit is quite feasible to dispense with this lever and insert the bentplate to begin with.

In the drawings the spindle of a wheel of a cycle is marked a, the rimw, and the tirecover y. The arm of my appliance (usually the inflaterpump-stem) is marked a, and b is an adjustable sleeve thereon, a clamp,setscrew, or any suitable means being used for temporarily fasteningthis sleeve firmly at whatever part of the arm a is found desirable.Projecting from this sleeve is a suitably bent orhooked plate, (marked0,) and opposite to it is a grooved wheel d, or it may be a broad wheelwith a flange on one side (the outer) only of any section which willhold and guide the tire-cover temporarily during the replacing operationand release it, as herein described.

In orderto remove the tire-cover y, it is necessary to slip one end ofthe spindle zinto a hole 6 in the lower end of a rod a (or of anattachment thereto, such as a fixed or adjustable sleeve a, thereon,Figs. 1 to 3) or into one of several such holes when a nu mber of themare provided to suit cycle-wheels of various diameters. The operatoralso slips the outer edge of the bent plate 0 under any point of thecover 3 (at which point it has preferably been already raised.) Theoperator then makes a revolution of the arm a on its center z, as perarrow in Fig. 2, and this action raises and disengages the edge of thetire-cover from the rim of the wheel. In the drawings the edge of thetire-cover where exposed (that is,clear of the rim 0c)is marked 3 Inorder to replace the tire-cover, the operator first slips the said coverover the rim of the wheel, tucking it in by hand as far as convenient.The appliance is then adjusted in position, with the flange (nearest tothe said cover) on the edge of wheel d beneath the edge of thetire-cover g as in Fig. 1, and the clampf (the lever of which is marked9) secured over the rim of the cycle-wheel, as in Fig. 2, to prevent thetire-cover slipping. In order that the wheel 01 may have the part whichgoes under the tire-cover projecting inward sufficiently to so guide thetire-cover edge as to release the latter, so that it shall fall withinthe rim 1 the said wheel (1 has its axle 61 set obliquely to the rod a,as shown. The arm a is then revolved on its center, and the successivepoints of the tire-cover will be found as they are released by wheel (Zto fall just above orv into their places within the rim to. Then as theedge of the tire-cover drops on or inside the rim it may be, ifdesirable, further depressed or tucked in by hand-pressure by theoperator, who can use for the purpose the thumb of the hand with whichhe is (at the same time) revolving the appliance. A convenient part ofthe rod a for the hand-grasp is marked a it being situated slightly moredistant from the eye or eyes 0 than the attach- 6o ment 1). The innertube of the tire is best partially inflated during the replacing of thetire-cover.

This invention need not make the infiater unwieldy, as the parts addedto it might be removable, so as to go into the cyclists toolbag. The eye0 need not be a close fit on the spindle or the like. Variousmodifications of other details might be made in this invention withoutdeparting from its scope.

That I claim as my invention, and desire to secure by Letters Patent ofthe United States, is

1. In an appliance for manipulating pneumatic tires of wheels, thecombination with the part a adapted to be attached to the axle of thewheel, of the adjustable sleeve or attachment I) having the plate or arm0 on one side, and the obliquely-set grooved wheel (I on the other side,substantially as and for the purposes set forth.

2. In an appliance for manipulating pneumatic tires of wheels, thecombination with (and near one end of) the stem of an inf-later, of anattachment or part adapted to be attached orpivoted to or on the axle ofthe wheel, and (at an adjustable distance therefrom on the said stem) asleeve or attachment having on one side a projection consisting of anysuitably bent or hooked plate, and on the side opposite saidprojection, a flanged or grooved wheel, all as and for the purposes setforth.

3. The combination with the inflater-stem a, of the adjustable sleeve orattachment 1), having the plate or arm 0 on one side, and theobliquely-set grooved wheel d on the other side substantially as and forthe purposes set forth.

4. The combination with a rod or inflaterstem a, of an attachment ahaving an eye or eyes c (adapted to fit over the spindle .2 of a wheel)and a sleeve or attachment I), having the plate 0 at one side and thegrooved wheel (Z at'theother, the distance of the sleeve orattachment 1) from the eye or eyes e being adjustable the said rod orstem having also a part or end (L (to be grasped by the operator) moredistant from the eye or eyes 6 than the said attachment b, so as toenable an external tire or cover to be removed and replacedsubstantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

ALBERT c. PALMER.
